<span style="font-weight: bolder;">5. Space Weather Effects on GNSS</span></h4>
<h4 dir="ltr" style="text-align: left; text-indent: 0px; line-height: 1.2; font-family: "Roboto Condensed", sans-serif; font-size: 24px; font-weight: 500; color: rgb(56, 56, 56);">
<span style="font-size: 16px;">Space weather events, caused by the coupling of solar wind into the magnetosphere and ionosphere (forcing from above) or by interactions between the lower thermosphere and ionosphere (forcing from below), significantly affect
various GNSS applications, including Positioning, Navigation, and Timing (PNT), communication systems, precision agriculture, and others applications. To effectively prepare for both short-term and long-term space weather impacts on modern society, it is crucial
to enhance our understanding of space weather physics, improve forecasting capabilities, and develop strategies to mitigate its effects on technological infrastructure.</span></h4>

<span style="font-size: 16px;">The goal of this session is to provide a platform for discussing space weather-driven ionospheric dynamics, particularly their impact on radio frequency applications. We welcome both observational and modeling contributions that
deepen our understanding of the complexities of space weather effects, including studies on the drivers of strong ionospheric dynamics during magnetically quiet periods. We also invite papers that introduce techniques for mitigating the impact of space weather
(with particular focus on low-latitude regions) on GNSS applications, including on the ground and space-based augmentation systems (SBAS/GBAS).</span></h4>
